GAR BOLSTER AND SIDE BEARING.

APPLIOATION FILED DEC. 30, 1910.

1,042A70 Patented 001129, 1912 WITNESSES IN ENTOR Cir To all whom it may concern it known that I, ALLEN E. @S'QEANDER, residing at Ritlgewoocl, Bergen county, New Jersey, and being a citizen of the United States, have invented certain new and. useful Improvements in Car-holsters an-Cl Side Bearings, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it pertains to make and to use the same, reiterence being had to the accompanying cleave ings, Which illustrate the preferred form of the invention, though it is to be understood that the invention is not limited to the e thereof will occur to persons skilled in th. art

In aid drawings: Figure 5 15 else vertical sectional View through 11 of tank car and illustrating in a holster constructed with the-i1 if applied thereto, parts said i being shown section l line 2-2 of Fig. 1 and locking in tion of the arrows The object or" the invention is to a holster construction to cars which is adapted to support the Weight of the superstructure and of the latlin'g carried thereby at points directly above, or in the lines of greatest compression atoms, the side bearings of the bolster, and further to form said side hearings with means for strengthening the vertical members of the holster along said lines of compression ani thus to render possible the lightening of the greater per tions of the bolster its sustaining qual iesl it further object. is to provide, in combination with the shove, 111*2218 formed upon each the sit hear ngs aclaotecl to serve as an anchor i it is obvious that the e v M applicable to any class ot cars wherein the hotly structure is independent of .azncl is sup ported. upon me holsters.

In the drawings 1 vention as being eppi do not Wish to he u myself to the accepted common to tank Referring to the parts hy numerals,

each sitle oil Without detracting; trons GAR .1101? OF NEW that. the holsters, with which the invention is partieulaicly coiicei'ne are disposed transversely of center sills in their usual positions adjacent opposite ends of said sills.

The holsters are ohviousy identitial and each is composed of spaced flanged diaphragms disposed. onepair upon the center sills and connected; by the usual top and bottom cover plates l and 5), "which cover plates extend transversely of the car above and below the cen-' ll u bottom flanges of the 1 turned outwardly anel the es anti 5 ere riveted thereto and 2 bottom flanges of the center I l of which is common in the art. The

. are iso illustrated.

" er surface of the top points spaced upon oppo site SlLlES the center sills, are supporting castings hit-turned flanges as 9E) re termed-upon the lower edge of each of the castings 8 and said flanges are fixed to the cover piate a; by some of the rivets which serve to connect said cover plate to the top flanges of the diaphragms 3. The upper surface of each of the castings 8 is curved to correspond with the curvature of the tank, or preterehlv to correspond to the curvature of a tank or the possible diameter, saicl curved surface is tornietl with a Les of or recesses as 10--10 adapt cal each to ve block as ii of cast iron, or any suitable material. The several blocks 11 are so progortionett and their upper surtaces so curved as to conform colely the curvature of a given size of larger or smaller tank Wlll reslifhtly ditlerent shape and ZNAZQLIJS points spaceci upon opposite s l oi as enter sill tie hearings as 6 and the center beau" transversely l inner side of the adjacent side bearings and cover plate and fixed thereto by some of the rivets as 14: whichfiX said cover plate to the fianges'of the diaphragm. Other rivets as,

14? extend only through said flange and through said cover plate between the webs of the diap'hragms.

Upon the side opposite the flange 13, each of the side bearings is formed with a flange 15 which flange is fixed at its opposite ends directly to the under faces of the adjacent lower flanges of the diaphragms- 3 by rivets as at 16. .Interr'nediate the webs of the diaphragms each of the flanges 15 is suitably reinforced and apertured as at 17 and adapted to serve as an anchor for the adjacent end of the usual tank bands as 18, which is extended through said aperture and held by a but as at 19.

Itshould be noted that the flange 15 may serve in a similar capacity as an anchor receiving member for anchoring a car body of any design suggested hereinbefore.

. Formed integral with each of the side bearings 12 is an upwardly projecting por-" tion as 20 which portion is. fitted between the spaced webs of the adjacent diaphragms 3 and is extended so'that an upper flange formed thereon as at 21 is made to, rest solidly against-the under surface of the top cover plate l at a point beneath the adjacent superposed casting 8, which point is in the line of greatest compression from the superposed structure of the car. The portion 20 is formed of a plate 22 with lateral J' side flanges 23-23, which flanges are disposedto be fixed to the webs of the adjacent diaphragms 3. Each of the flanges 28; also the plate 22, have their upper ends merging into the top flange 21 and their lower ends merging into the body portion of the side bearings and said plate and flanges are disposed so as to follow said line of greatest compression and thus to materially assist the side vertical members or diaphragms of the bolster in withstanding the excessive stresses to which they are subjected as a result of the natural tendency of the car body to tilt to one side or the other, which tend ency is most apparent when the ca is passing around a curve in the track.

The castings 8 are made hollow so as to re duce the-weight thereof and the surrounding walls may be reinforced by any desirable form of webs or braces, but each castingis preferably formed with a heavy rib as 24:

disposed transversely of the bolster'so as'to rest in positive contact with the upper surfaces of the cover plate 4: at a point in the line of compression above the top flange of the portion 20 of the adjacent side bearing so as to more directly transfer the weight of the superstructure to the side bearings.
